Understanding the compound risk of heat, humidity and air pollution on human health: A scoping review

This study by the Red Cross Red Crescent Climate Centre warns for the compound exposure to heat, humidity and air pollution, which lead to worse health outcomes in terms of mortality, cardiovascular, respiratory and pulmonary conditions, kidney function, birth complications, and physiological or cognitive functions. Complex interactions between temperature and environmental variables need to be considered for extreme heat policy and interventions to reduce the health impacts of extreme heat accurately and efficiently. Notwithstanding the gravity of the compound effects, knowledge in this area is too limited and should be more granular and focused on various potential health outcomes.
